## Abstract

The EPA is taking direct final action approving the State Implementation Plan (SIP) revisions for Bernalillo County, New Mexico, which is a carbon monoxide maintenance area. This SIP revision was submitted to EPA by the Governor of New Mexico on May 15, 2003. More specifically, EPA is approving the county's revised Motor Vehicle Emissions Budget (MVEB) for carbon monoxide (CO) for 1996, 1999, 2002, 2005 and 2006. This budget was developed using EPA's latest emissions modeling program, MOBILE6. This submittal updates the maintenance plan by establishing new transportation conformity MVEBs for use by the Mid- Region Council of Governments, the area's Metropolitan Planning Organization (MPO). These budgets will continue to maintain the total on-road mobile source emissions for the area at or below the attainment level for the CO National Ambient Air Quality Standard (NAAQS).
